Most unhealthy dog breeds

These are potentially the unhealthiest dog breeds. We used research from Dr. Marty Becker, a 2003 study, and a host of other resources to compile this list.

If you have a dog from this list, then we strongly recommend you look into getting a pet insurance policy from Lemonade Pet Insurance or another reputable insurance company. Even healthy dogs from this list of breeds are likely to run into health issues sooner or later, so it’s important to make sure you’re protected.

Bernese Mountain Dog

Proud to be the only Swiss mountain dog, The Bernese Mountain Dog is a purebred and may be a descendant of the inbreeding of native flock-guarding dogs and Roman Mastiffs. They belong to the Working group. According to the 2003 study linked above, Bernese Mountain Dogs have a median lifespan of seven years, making them one of the dog breeds with the shortest lifespans. 

They are susceptible to a host of health concerns, some minor and others serious. Among many, these problems include: cancer, kidney disease, liver disease, gastric torsion, Addison’s disease, Hemolytic Anemia and Thrombocytopenia, Bloat, and joint diseases.

Of course, this doesn’t mean your Bernie can’t live a happy, relatively healthy life. You should just make sure to keep an eye on these issues with help from your veterinarian.

French Bulldog


French Bulldogs are a purebred breed and part of the Non-sporting group. They also belong to a smaller group of dogs called the Brachycephalic group, which are flat-faced breeds. Their short nose leads them to have upper airway dysfunction and obstruction, which can cause breathing issues. They have an average lifespan of 9 to 11 years. They’re prone to intervertebral disk disease (IVDD), allergies, patella luxation, skin fold dermatitis, hip dysplasia, and heat stroke. This breed delivers offspring by Cesarean section.

Some critics consider French Bulldogs an unethical dog breed since they were bred predominantly for looks rather than health—hence the frequent breathing and birthing issues. The Dog Tale doesn’t apply any ethical judgment to the breed one way or the other. If you have one, try to give them the best care possible. If you want one but don’t want to support unhealthy breeding, then we encourage you to try rescuing a Frenchie from your local shelter.

English Bulldog

Like the French Bulldog, this purebred is another Brachycephalic dog breed. They belong to the Non-sporting class of dogs. Their average lifespan is 8 to 12 years. Dr. Becker states that the “exaggerated features of the Bulldog and other related breeds have produced a perfect storm of health problems that diminish the quality of life for many of these dogs, and often make them extremely expensive to own.” 

Since their nostrils are narrow, and their soft palate longer, the Bulldog can have severe breathing problems, especially when it becomes overheated or excited. They are also predisposed to obesity, which can put too much weight on their joints.

Are there ​​dog breeds that shouldn’t exist?

The belief that certain breeds shouldn’t exist or that there are unethical dog breeds is a matter of opinion.

It’s difficult to apply moral absolutes to the mere existence of some animals. However, certain breeds are a cause for concern. For example, because of how French Bulldogs are bred, they almost always have to deliver their young by cesarean section. The fact that Golden Retrievers have earned the unfortunate nickname “The Cancer Retriever” is also unsettling.

In her social media post titled, “What vets really think about which dog you should buy” Veterinarian Cat Henstridge warns against certain canine characteristics and traits that are prone to disease or aren’t family-friendly to the average pet owner.

Dogs to avoid:

  1. Any dog in the brachycephalic group: Short-muzzled dogs with a flattened face. E.g. French Bulldog, Boxer, Pug, Boston Terrier, English Bulldog, Pekingese, etc.
  2. Any dog in the chondrodystrophic group: Breeds have the short leg, long body look. E.g.  Dachshunds, Basset Hounds, Beagles, Corgis, English Bulldogs, etc.
  3. Dogs with an adult size smaller than a cat or bigger than a newborn calf
  4. Any breed from a working stock (unless you can provide it with proper exercise)
  5. Dogs that are smarter than you!
  6. Breeds that were used for gripping, guarding, or fighting
  7. Breeds known as “feisty,” “aloof,” or “fiercely loyal”
  8. Shar Peis
  9. English Bulldogs
  10. Teacup versions of any breed
  11. A breed with a disease named after it
  12. Dogs that are likely to develop neoplasia, (i.e. abnormal tissue growth)
  13. Dogs that cost more because of its special color. E.g. a “Chocolate Yorkie” or “White Yorkie
  14. Dogs that have an average lifespan lower than your shoe size

How to avoid getting an unhealthy dog

Get your dog from reputable sources

If you rescue a dog from a shelter, there’s no guarantee it will be healthy. But that shouldn’t deter you. Adopting a shelter dog that needs a home can be an ethical (and affordable!) way to add a companion to your family. You can help increase your chance of getting a healthy dog by asking the shelter questions about the health examinations they’ve had on the dogs and any current health issues. Learn more in our guide to adopting vs buying a dog.

If you choose to get your puppy from a breeder, you’ll want to get a full picture of the puppy’s background. A reputable breeder should allow you to see the puppy and its mother as well as provide you with health information about the puppy, the parents, the grandparents, their lineage, and more. 

Ask what tests were done on both parents for common breed issues such as hip scoring or heart issues. A good breeder will use selective breeding to mitigate these problems. Additionally, ask the breeder for references from previous adoptive families to get their take on the breeder and to find out if their dog has any hereditary conditions.

Give your dog a healthy diet

Possibly more important than genetics is nutrition. Feeding your pet a nutritious diet can have profound effects on their health, like creating a strong immune system that can fight off disease.

Too often, traditional dog food lacks real nutrition due to low-quality ingredients, over-processed cooking methods, and fake preservatives added to make it shelf-stable.

If it’s within your budget, fresh, human-grade food like The Farmer’s Dog or Nom Nom Dog Food are some of the healthiest choices available, since their minimal cooking methods and fresh ingredients maximize the bioavailable nutrients for your dog’s body to absorb. Premium kibbles like Spot & Tango’s UnKibble, Ollie’s Baked baked dog food, or Sundays Dog Food are also great options since they start with real food ingredients.

Get pet insurance

Regardless of your dog’s breed or the diet you feed them, they can and probably will still get sick or injured at some point in their lives. We’ve fed our Yorkie a healthy diet from the beginning, but a healthy diet didn’t prevent him from breaking his leg when he was a puppy.

A pet insurance policy, such as Lemonade Pet Insurance, can help at a time like this. Having a policy in place before you need one could help cover unexpected vet bills that accrue so quickly with an illness or accident.
